''w_scan'' is a small command line utility used to perform [[Frequency scan|frequency scan]]s for [[DVB]] and [[ATSC]] transmissions. It is not included in [[LinuxTV dvb-apps]] but complements the two [[Frequency scan|frequency scanning]] utilities available through [[LinuxTV dvb-apps]], [[Dvbscan|dvbscan]] and [[Scan|scan]].

Obtaining w_scan

Documentation

Detailed information can be found in the w_scan man page (i.e. from a console, run man w_scan). Additionally, running w_scan with the -h parameter will produce an output that provides a summary of it's main command line options.

w_scan [options...] >> channels.conf

In general, when using w_scan you should at least specify three parameters: frontend type, country/satellite and output format. The following table summarizes the basic command line essentials for using w_scan.

Some working examples, cobbled together from the basics given in the above table, are provided below. Note: Experts or experienced users may use some of the other w_scan options available, but this is not recommended. (For example, w_scan searches /dev/dvb/adapterX/frontendY for DVB/ATSC cards matching to option "-f", therefore specifying the adapter "-a XX" is not recommended.)
